A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Swamp coolers.

Fans blow over water to lower the pressure, causing evaporation to occur at room temperature.

Evaporating water absorbs heat from its surroundings without raising the water's temperature as it undergoes a phase change. It absorbs nearly 20 times more heat than it would from being heated from 50 degrees F to 100 degrees.
